roles/nginx: Add fastcgi caching 
Bypasses caching for logged in users (right now only for sessions
where the "wordpress_logged_in" cookie is set. Doubles the trans-
actions per second as measured by siege:

Amazon EC2 or OpenStack images where the first user is `ubuntu' and
you can't assume `provisioning' is already created.

Move Debian.yml vars to Ubuntu.yml 
I was using ansible_os_family to get settings for Debian-family
hosts, but this doesn't work so well when you have an apt_mirror
which is only Debian or Ubuntu, for example.

I don't have any Debian hosts here, but anyways, it's better this
way so I can be more flexible in the future.

6ccfdb99fa roles/nginx: Enable OCSP stapling 
Reduces round trip time for clients. Note: I am using a certificate
chain in the `ssl_certificate' directive, so as I understand it, I
don't need to use an explicit trusted intermediate + root CA cert
with the `ssl_trusted_certificate' option. See the nginx docs for
more[0]. Addresses GitHub Issue #5.

Seems to be working, test with:

    $ openssl s_client -connect mjanja.ch:443 -servername mjanja.ch -tls1 -tlsextdebug -status

Look for "OCSP Response" with "Cert Status: good".

roles/nginx: Set nginx SSL session timeout to 24 hours 
Default is 5 minutes, but it seems like unless you're a high-traff-
ic site, there's no need to expire sessions so quickly.  Also, the
istlsfastyet.com configs are using 24 hours, so surely we can.

roles/nginx: Adjust Cache-Control headers 
Use "public" with "max-age" instead of Expires, as "max-age" is always
preferred if it's present.  Note: setting "public" doesn't make the
resource "more cacheable", but it is just more explicit.

Downgrade TLS configuration to Mozilla's "intermediate" spec

when using the "modern" spec, I think I'd be doing more harm than
